In large bowl, dissolve 1 tsp sugar in warm water (110-115°F). Stir in yeast; let stand for 10 minutes, or until foamy. Whisk in 1 cup flour, oil and salt; beat until smooth.

Using wooden spoon, gradually stir in enough of remaining flour to make soft dough. Turn out onto lightly floured surface; knead for 7-10 minutes or until smooth and elastic, adding more flour if necessary.
